Issue with Google Map zoom

Hello,

I have read numerous threads on Community on setting up a Google Map within Qlikview, which I had done previously.

Our project has now been re-visited and when I try to generate the map with a new API key, the map just focuses on the entire globe, although the plots seem to point to the map locations I'd like.

I have a Geocoded table that would join by Zip Code

here's the map code:

// number of seconds to wait for a URL datasource

set OpenUrlTimeout=10;

gmap_key = 'xxxxx';

max_zoom_level = 14; //maximum value 17

// Variables required for calculating map

// No need to change these

var_pi180= '=pi()/180';

var_lat_offset= '0';

var_mc2= '=256*pow(2,$(var_zoom))';

var_mc1= '=256*pow(2,($(var_zoom)-1))';

var_mid_lat= '=min(latitude)+(1+var_lat_offset)*((max(latitude)-min(latitude))/2)';

var_mid_long= '=min(longitude)+(max(longitude)-min(longitude))/2';

var_zoom= '=max(aggr(if(max( round(256*pow(2,(_zoom_level -1)))+( longitude  *((256*pow(2,_zoom_level ))/360)) )-min( round(256*pow(2,(_zoom_level -1)))+

( longitude  *((256*pow(2,_zoom_level ))/360)) ) <map_size_x AND max((256*pow(2,(_zoom_level-1)))+((0.5*log((1+(sin((latitude)*pi()/180)))/(1-(sin((latitude)*pi()/180)))))*((-256*pow(2,_zoom_level))/(2*pi()))))-min((256*pow(2,(_zoom_level-1)))

+((0.5*log((1+(sin((latitude)*pi()/180)))/(1-(sin((latitude)*pi()/180)))))*((-256*pow(2,_zoom_level))/(2*pi()))))<map_size_y,_zoom_level,1),_zoom_level))';

var_maptype= '=if(isnull(only(maptype)),fieldvalue( '&chr(39)&'maptype'&chr(39)&', 1 ),maptype)';

map_size_x=    '600';

map_size_y=     '400';

//var_maptype = '=if(isnull(only(maptype)),fieldvalue( '&chr(39)&'maptype'&chr(39)&', 1 ),maptype)';

vMinXaxis       = ' (256*pow(2,((var_zoom)-1)))+((var_mid_long)*((256*pow(2,(var_zoom)))/360))-(def_map_size*0.5)';

vMaxXaxis = '((256*pow(2,((var_zoom)-1)))+((var_mid_long)*((256*pow(2,(var_zoom)))/360))+(def_map_size*0.5))';

vMinYaxis = '((256*pow(2,((var_zoom)-1)))+((0.5*log((1+(sin((var_mid_lat)*pi()/180)))/(1-(sin((var_mid_lat)*pi()/180)))))*((-256*pow(2,(var_zoom)))/(2*pi())))+(def_map_size*0.5))';

vMaxYaxis = '((256*pow(2,((var_zoom)-1)))+((0.5*log((1+(sin((var_mid_lat)*pi()/180)))/(1-(sin((var_mid_lat)*pi()/180)))))*((-256*pow(2,(var_zoom)))/(2*pi())))-(def_map_size*0.5))';

SET HidePrefix='_' ;

// Field required for calcualting best zoom level

_zoom_level:

Load RecNo( ) as _zoom_level autogenerate(max_zoom_level);

//inline load for various map types

maptype:

Scale x-axis

(256*pow(2,($(var_zoom)-1)))+( var_mid_long  *((256*pow(2,$(var_zoom)))/360)) -round(map_size_x/2)

( (256*pow(2,($(var_zoom)-1)))+( var_mid_long  *((256*pow(2,$(var_zoom)))/360)) + round(map_size_x/2)-15)

Scale y-axis

((256*pow(2,($(var_zoom)-1)))+((0.5*log((1+(sin(var_mid_lat*pi()/180)))/(1-(sin(var_mid_lat*pi()/180)))))*((-256*pow(2,$(var_zoom)))/(2*pi())))+round(map_size_y/2))

Is there some adjustments in the map I'm missing that the map does not focus to the locations I'm setting the slider bar to?
